LOCOMOTIVE-TENDER TRUCK.

Specification of Letters Patent.

Patented Feb. 23, 1909.

To all whom it may concern:

Be it known that I, WILLIAM L. AUsTIN, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Locomotive-Tender Trucks, of which the following isaspecification.

The object of my invention is to construct a swinging truck for useunder the tender of a locomotive and to provide the bolster with sidebearin plates so that the movewhich ismounted the bolster ment of theten er will be resisted by the bolster rather than by the frame of thetruck as heretofore. This object I attain in the following manner,reference being had to the accompanying drawings, in which Figure 1, isa side view of a tender truck illustrating my invention; Fig. 2, is atransverse sectional view on the line 2-2, Fig. 1; Fig. 3, is a planview of the central portion of the truck, and Fig. 4, is a detachedperspective view of the bolster.

A is the frame of the truck having pedes tals a for the boxes 0.

B, B are the axles on which are mounted the wheels b.

i D, D are longitudinal bars extending on each side of the side membersof the frame and resting upon the boxes c, as shown in Fig. 1. Suspendedfrom these bars are stirrupsd on which are mounted the springs D.

plate F connected to the body frame F of the tender. The bolster alsohas side bear-' ing platesE which may be integral with the bolster orsecured to it as desired. The plates E are directly below the plgates fon the tender frame and take the aring of these plates. The bolster hasa deep'flange on each side. as ,i l1ustrated in Fig. 3, and

1 each flange is perforated at c-e for the passage of pivot pins G towhich are attached the links z hung from pins I extending throughopenings in the transverse member A of the truck frame A.

In order to allow for the free movement of the bolster in the frame, Iform elongated openings e in the flanges of the bolster E. The pivotpins I extend through the bolster and through the side plates of theframe A as illustrated in Fig. 3. It will be seen that thereare nosprings between the tender body and the frame of the truck; the bolsterbeing connected directly to the frame by links so as to allow'it tofreely swing, the side bearing plates being on the bolster and thesprings are mounted between the truck frame and the boxes for the axles.

I claim 1. A bolster for a truck frame to be placed under the tenderbody, consisting of a body portion with deep flanges at each side,openings in the flanges for the passage of the pivot pins by which thebolster is hung from.

the body of the truck, a center bearing pocket formed in the bolster,and side bearings on each end of the bolster.

2. The combination of a tender body having a center bearing plate andside bearing plates, a truck frame, boxes and axles,

springs mounted between the frame and the boxes, a swing bolster mountedin the transverse member of the truck frame, said bolster having deepside flanges, links on each side of the bolster and pivoted thereto,pivot pins connecting the upper ortions of the links to the truck frame,sai bolster having enlarged openings for the passage of the upper pivotpins to allow the bolster to swing, and a center bearing and sidehearings on the bolster.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
